REFUSE-BURNER.

To all whore; it may concern Be it known that I, JESSE Pnnsoo'r'r, a citizen of the United States, and resident ot Webster, in the county of Worcester and State of Massachusetts, have invented an Improvement in Refuse-Burners, of which the following description, in connection with the accompanying drawings, is a specifica# tion, like letters on the drawings representing `like parts.

This invention relates to burners for the consumption of various forms of household and other garbage and refuse, of the type shown in my copending application Serial No. 708,512. A

The present burner is of a type adapted to' receive and hold accumulations of gan bagc in amanner to permit the drying out ci the same by air currents passing up therethrough, and is provided with a gas burner arranged in connection with a special form of grates to direct the heat and flame over and through all parts of the garbage mass so that the combustion et the garbage of open-work zontal grate 18,

is quickly initiated and completed.

'The invention will from the 'following detailed description, taken in connection with the' accompanying drawings, and will be thereafter pointed out in the appended clainis.

Referring to the drawings, central vertical section proved incinerator through'the middle of the doors and-staclr-eonnection; and'llig. 2 shows in top plan, on a reducedv scale, lthe upper part of the grate structure, the adjacent supports and shells being sectioned ttor convenience of illustration.

'The burner casing is preferably rectangular and comprises spaced apart inner an outer shells 10, 12 itted 111, the annular space between the ,shells serving for heat insulation. The inner shell or receptacle, as shown, does notextend down to the base at the front, but fits a flange 13 inwardly projecting from the outer shell. An ash-pan 14C resting on the base is 'removable through a lower door 15, this doorbeing Figure. 1 is a mesh 16 stretched thereacross. A. lange eX- tends inwardly om the receptacle 12 as seen at 17, to provide a support for a horiwhic'h is of slotted construction as seen at 19 and which may, if desired, have suitable dumping provision. A gas supply pipe 2O extends up through a cen- Specllcaton of Letters Patent. Application filed November 22, 1911.

construction protected by fine Patented Feb. 10, 1914. serial no. 661,756.

tral aperture 21 of the horizontal grate to fit into a burner 22 having a diverging conical portion with a circular series of slits 23 adapted to project the 'flame downwardly and outwardly through the slots 19 of the grate. A tall conical hood 24 extending well up into the receptacle space .closes the top ofthe diverging conical portion'22, and

this hood preferably extends on down below' its junction with the portion 22 as an outwardly flaring-rim 25 adapted to aid in the direction of the annulus of la'medownward and outward. v .An upwardly, outwardly flaring openwork grate with the horizontal grate 18, a suitable interlocking connection 27 bei-ng shown `between these grates. This flaring grate porat 2S, and, at this part, ot a size 'so as to be spaced away from the extremity 25 of the central hood some little distance. This grate changes to a rectangular cross-section at its upper part, and a top spaeedaway 'from the receptacle 12 to leave a peripheral space sufficient for the passage of the flame and heated currents therearound.

A vertical openwork square in cross section'extends upward from the top 29 ot the flaring grate, this being spaced away from the receptacle 12 simi-` larly to the top of the flaring grateso that a space around the grate construction is provided up to the top bf the vertical grate 30, at which p'oint the portion 26 engages grate portion Q3()V receptacle 12 is provided with a ledge or shoulder 31, the inner edge of which lits the'fvertical grate. Both number of sections, shown as oi: division between sections being indicate assembled in the casing.' As there is seldom occasion for disturbing the vertical ygrate v30, this may bel permanently secured and positioned in the inner receptacle, as by suitable lugs 33. As itniay be ldesirable to remove the lower `flaring grate at more or less trequent intervals for clearing out or other the portions of this are preferably lfor convenient remova the doors 34 adjacent thereto. A suitable dumping door-3.5 is pivoted in the top portion of the casing zit-36 a short distance above the top of 'the vertical ygrate .'30, and

arranged so that the gratas maybe conveniently through 2O garbage within this portion.

Q' l abscess in the hase, so that the drying-out of the gar-y bage is greatly expedited. The screen mesh 16 litted to the Ventilating openings in the l lo-Wer door eifectually prevents the entrance of flies and vermin. rlhis dryingrout action is promotedby reason of the outwardly flaring portion 26, which causes the air currents to impinge to a greater extent. against the Likewise, when the gas is ignited, the outwardly pron ject-ed annulus of flame spreads over and up along the flaring openwork portion to Y quickly and effectively attack the garbage and, as the heated currents pass upward, being confined in the relatively narrow peripheral space between the receptacle 1Q- and the vertical grate 307 they tend to converge inward through the slots in the vertical grate 3o to attack the upper part -of the garbage. This action is promoted by reason of the fact that the top of this peripheral space is closed `by the shoulder 3l so that avent out-let must be found through some portions of the top of the vertical grate. The conical hood 24 extending up centrally within the receptacle space carries the heat well up into the center of the garbage mass, thus dessicating the center of the mass at the same time that the flame is attacking the periphery thereof.

The incinerator thus constructed is especially" well adapted for promoting and quickly effecting the preliminary drying-out of thegarbagc while it is accumulating and being stored in the receptacle by the circulation oft-he air currents up through the rcvc'eptacle, and the continuous opeuwork construction of the upstanding grate composed of the flaring portion 2G and the straight vertical portion 30 enables the burner flame to at tack the garbage much more effectively in all parts thereof than 'has been the case in previous incinerators known to me. l

I am aware that various of the .details of construction may be varied without departing from the spirit of the invention, and I therefore do not desire to be limited as to these or in any other particulars `creep t as set forth in the appended claims.

Having described my invention, what l claim as new and desire to secure by Letters Patent is:

l, An apparatusy of the kind described,v

comprising an upright receptacle for gan bag@ or the like having a normally closed opening for thev admission of garbage adja-- cent the top of the receptacle, Aan openwork grate thcrewithin composed oi' va bottom portion, a separately removable outwardly ilai ing portion, and a 'separately removable vei-- tical portion forming a continuation of said outwardly flaring portion, said vertical por tion extending to substantially the bottom of said opening at the top of the garbageholding portion of the receptacle, and the rcceptacle having an inwardly extending shoulder meeting the top of said grate.

2. An apparatus of the kind described, comprising an upright receptacle for recoiving and burning garbage,- or the like, having an openwork grate therein composed of a bottom portion, a Haring side portion in a plurality of sections, and a substantially vertical portion in a plurality of sections, r'said vertical portion being adapted to be permanently secured to the sides of a receptacle independently of the flaring portions, while forming substantially a continuation thereof and both flaring and vertical por tions being independently removable from the receptacle.

In testiinony whereof, I(l have signed my name to this specification, in the presence of two subscribing witnesses.

y JESSE PRESCOTT.
